Bladeweaver

The phrase "Swords meet Sorcery" has been uttered by many a spellcaster when facing weapon-wielding foes (most notably the wizard Gale of Waterdeep), but you have decided to take the saying literally and weave your magic and martial prowess into a symphony of devastation.

Bonus Proficiencies, Fighting Style

Also at 1st level, you gain 1 fighting style from the Fighter List.

Weave-Born Combatant

As magic flows through your body, and your martial prowess manifests, your path as a Bladeweaver has begun. At 1st level, whenever you take damage, you can reduce that damage by a number equal to your Charisma modifier (minimum of 1), you also automatically learn either the Booming Blade or Green-Flame Blade cantrips.

Additionally, your inborn magic forms a bond to your martial weapons and vice versa, whenever you finish a long rest, you can form a bond with any weapon you are proficient with, making it a Weavebound weapon, until your next long rest, you can use your Charisma modifier to attack and damage rolls made with that weapon, that weapon can be used as your spellcasting focus, you cannot be disarmed from that weapon, you can summon that weapon to your hand at will (And returns to your hand when thrown), and that weapon becomes magical for the purpose of overcoming resistances and immunities.

You also gain an additional reaction each turn, this reaction can only be used for making an Oppertunity attack with your Weavebound weapon, and you can still only make 1 Oppertunity attack per round.

Magical Infusion

At 14th level, your connection to the weave forms a closer bond to your weapons and armor, whenever you are concentrating on a spell, your weavebound weapon deals an extra 2d4 damage, you also reduce all damage taken by 1d4 and add 1d4 to all saving throws.

Master Of Martial Magic

Beginning at 18th level, Whenever you cast a spell as an action, you can cast one Cantrip as part of that same action. Additionally, whenever you cast a spell in combat your next attack with your Weavebound Weapon adds an extra number of d10 to the damage roll equal to the spell's level, this extra damage can only occur once per round.
